Nutating internal combustion engine

A nutating-disc, internal combustion engine comprising:

• a nutating-disc having cone-shaped surfaces and a centrally disposed sphere, said disc having two gaps and an edge containing a pair of seals to contain oil for lubrication and cooling;
• said sphere having a crankshaft rotationally disposed on the axis of said disc and having a bearing for said crankshaft;
• a symmetrical, spherical-segment shaped chamber adapted to contain said sphere and disc, said chamber having a central bearing to movably engage said sphere and to allow said disc to nutate within said chamber;
• drive shafts disposed on the axis of said chamber positioned on both sides of said chamber, said drive shafts being eccentrically affixed to said crankshaft whereby the crankshaft is positioned at an angle with respect to the drive shafts such that the nutating motion of said disc causes said drive shafts to turn;
• said chamber having two stops aligned with said gaps in said disc, said stops, along with said centrally disposed sphere, divide said chamber into an intake/compression portion and a combustion/exhaust portion, wherein one of said stops includes a fuel input means and one of said stops includes a passage to transmit oil to the sphere and disc to lubricate and cool the engine, and one of said stops includes an air intake means;
• said chamber having two flat surfaces disposed perpendicular to said drive shafts said surface containing a plurality of exhaust ports to exhaust gas from said combustion/exhaust portion;
• said disc having a first portion and a second portion, wherein said disc first portion divides said intake/compression portion into at least two sections and said second disc portion divides said combustion/exhaust portion into at least two sections;
• and
• a fuel injection system including an accumulator adapted to store compressed air from said intake/compression sections, a pre-chamber, means to inject stored compressed air into said pre-chamber, a first means to inject fuel into said pre-chamber and means to ignite the fuel-air mixture.

A nutating-disc, internal combustion engine comprising:

• a nutating-disc having cone-shaped surfaces and a centrally disposed sphere, said disc having two gaps positioned 180 degrees apart;
• said centrally disposed having a shaft positioned therein to contain a crankshaft rotationally disposed on the axis of said disc wherein said center of mass of said centrally disposed sphere and disc is stationary at all times;
• a symmetrical, spherical-segment shaped chamber adapted to contain said disc, said chamber having a central bearing positioned to movably engage said sphere and to allow said disc to nutate within said chamber;
• drive shafts disposed on the axis of said chamber positioned on both sides of said chamber, said drive shafts being eccentrically affixed to said crankshaft whereby the crankshaft is positioned at an angle with respect to the drive shafts such that the nutating motion of said disc causes said drive shafts to turn;
• said chamber having two stops aligned with said gaps in said disc, which along with said centrally disposed sphere, divide said chamber into an intake/compression portion and a combustion/exhaust portion, said first step arranged to inject fuel to at least one portion and to inject oil into said sphere and disc for cooling, and said second stop arranged to inject air to said chamber;
• said chamber having two flat surfaces disposed perpendicular to said drive shafts and having a plurality of exhaust ports to exhaust gas from said combustion/exhaust portion;
• an exhaust manifold coupled to said exhaust ports to provide an outlet from said exhaust ports;
• said disc having a first portion and a second portion, whereby said disc first portion divides said intake/compression portion into at least two sections and said disc second portion divides said combustion/exhaust portion into at least two sections;
• said disc having an edge containing a first sealing means including a pair of c-ring seals to provide a seal between the disc and the spherical segmented walls of the chamber and to contain oil for lubrication and cooling, a second sealing means between the disc and the step, a third sealing means positioned within the chamber to seal the sphere within the chamber and a fourth sealing means having four seals positioned within each stop to seal the sphere within the chamber;
• a first cooling means for cooling the intake/compression portion to cause the intake/compression portion to operate at a lower temperature than the combustion/exhaust portion;
• a second cooling means wherein said stops includes passages to transmit a coolant to a series of passages within the sphere and disc to lubricate and cool the engine;
• an air intake means for providing air to the internal combustion engine;
• a fuel injection system including a fuel input for providing fuel to said fuel injection system, a pre-chamber, an accumulator adapted to store compressed air from the intake/compression portion, a first injection means to combine stored compressed air with fuel to form a lean mixture and inject the combined lean air-fuel mixture into said pre-chamber, a second injection means to inject an additional charge of fuel to said air-fuel mixture within said pre-chamber to form a stratified charge for more efficient firing and a spark plug to ignite the stratified charge;
• and
• an electronic control means to monitor the pressure of the air in said accumulator, the volume of a combustion section within said combustion/exhaust portion and timing of igniting of said stratified charge.
